Meaning
Audit procedure used to confirm the volume and origin of plastic waste processed through molecular breakdown rather than mechanical grinding. Chemical recycling verification ensures that a specific quantity of pyrolysis oil or monomer actually entered a production stream. It stops at the point where the material is converted back into virgin-grade resin.
Chain Custody
Tracking the flow of material through a complex chemical plant requires a rigorous accounting system. The chemical recycling verification process links the input of waste plastic to the output of new polymer pellets using a mass balance approach. This ensures that the environmental claims made by a manufacturer are supported by physical evidence of feedstock substitution.
Mass Balance
Allocation of recycled content to specific products follows strict mathematical rules. Auditors check the chemical recycling verification records to ensure that the total amount of recycled resin sold does not exceed the amount of waste plastic processed. This prevents the inflation of sustainability metrics and maintains trust in the circular economy.
Audit Reliability
Third party inspectors verify the data to provide an unbiased assessment of the recycling claims. The chemical recycling verification standard requires transparent documentation of every transfer within the supply chain. Successful completion of this audit allows a company to apply recognized sustainability labels to its products and satisfy the requirements of brand owners who demand proof of recycled content.
This verification reduces the risk of legal challenges regarding greenwashing and provides a clear pathway for companies to demonstrate their commitment to reducing the use of virgin fossil fuels in plastic production.
